Trial HSUPA handset to handset call completed
Nortel has managed to complete successfully the industry's first HSUPA call between two mobile phones. High Speed Uplink Packet Access (HSUPA) allows uplink speeds about four times faster than current UMTS services. Using its commercial UMTS Base Transceiver Station and Aeroflex's TM500 handset simulator, Nortel managed not only to make a VOIP call between two handsets, but also to transfer video and data. The uplink speeds, reached during the trial, are 1.4 Mbps. This trial reveals the potential of HSUPA, which will allow VOIP calling, video streaming, real-time high-definition mobile gaming as well as large file exchange. Nortel's HSUPA is expected to be available to carriers in the beginning of 2007.
